Alex Loddengaard updated HADOOP-6248:
-------------------------------------

    Attachment: HADOOP-6248_v2.diff

Attaching a new patch with a few modifications:
# Changed the canned distribution, which was previously Cloudera's 
distribution, and is now vanilla Hadoop.
# Changed hdfs-basic tests to not use /etc/passwd and instead create a 
temporary file
# bin/circus will now exit with the appropriate exit status when tests pass or 
fail

I should also say a little about my intentions of this patch, and Circus in 
general.  I claim that the code I've attached is preliminary, and my proposal 
has lots of open questions.  I'm confident that Circus, as it exists right now, 
is already useful for Hadoop users and QA engineers.  My posed questions are 
intended to gather useful feedback to improve Circus even more.  I'd be 
completely happy if the preliminary code made it into trunk, with the 
expectation that I will continue to submit further patches to improve Circus.

Thanks.

> This issue contains a proposal and preliminary source code for Circus, a 
> Hadoop system testing framework.  At a high level, Circus will help Hadoop 
> users and QA engineers to run system tests on a configurable Hadoop cluster, 
> or distribution of Hadoop.  See the comment below for the proposal itself.
